Locate the interior power distribution unit under the driver-side dashboard and verify each circuit using the printed layout before replacing any burned insert. Always match the amperage rating shown on the component to prevent wiring damage or malfunction.
This vehicle uses two main distribution points: one inside the cabin and another in the engine compartment. Each slot corresponds to a specific circuit, covering systems such as lighting, ignition, radio, and climate control, with ratings typically ranging from 5A to 40A.
The interior unit handles most electronic and accessory circuits, while the engine bay unit supports higher-load components such as cooling fans and charging systems. Identifying the correct layout allows fast isolation of faults like power loss or non-working accessories.
Check continuity with a multimeter rather than relying only on visual inspection, as internal breaks are not always visible. Loose contacts, corrosion, or heat discoloration near terminals often indicate the actual source of electrical issues.

Match each slot in the interior and engine compartment distribution units with its assigned circuit using the printed layout, then confirm amperage before installing a replacement insert. Typical ratings range from 5A for lighting and control modules up to 40A for high-load components such as cooling fans and power accessories.
Follow this check sequence:
- Locate the correct distribution unit by system area
- Identify slot number from layout chart
- Verify amperage printed on the insert
- Test continuity using a multimeter
- Check voltage on both terminals under load
- Inspect contacts for corrosion or heat damage
Interior circuits handle systems like radio, dashboard cluster, and signals, while engine bay circuits support charging and cooling. If repeated failures occur, inspect wiring near door hinges, under-dash harness paths, and firewall pass-through points where insulation wear is common.

Check the driver-side lower dashboard first, just above the footwell near the kick panel, where the main interior distribution unit is mounted behind a removable cover.
Access requires no tools in most cases–pull the plastic cover outward to expose the slot array. A layout chart is printed on the reverse side, showing circuit assignments and amperage values.
This interior unit handles lighting, signals, radio, and control modules, with grouped slots arranged in rows for quick identification.
Open the hood and locate the second distribution unit near the battery on the driver-side fender area. This section supports high-current circuits such as cooling fans and charging system components.
Ensure both covers are securely reinstalled after inspection to protect terminals from moisture and maintain stable electrical connections.
